Float Control Valves

Features

This valve maintains constant liquid level in a tank. The pilot is sensitive to slight changes in level. The main valve open when level drops and closes when level rises. The valve consists of basic valve and buoyancy pilot and controls the outflow in a water tank supply. It is installed on the inlet of a water pool or tower. 100X Float Control Valves is controlled by the floating pilot valves to close the inlet to stop water supply when the water level gets to the preset height and to open the inlet to supply water to the water tower or pool when the water level is lower than the preset one, so as to realize the automatic water control according to the changing water level. It features by the high accuracy of level control, water pressure disturbance resisting, mountable on any positions, reliable seal performance, easy installation, maintenance, debugging and check, long duration (The floating pilot valve can be separately mounted from the main one).
